Which of the following types of light cannot be studied with telescopes on the ground?

The Answer is X-rays

Explanation:

Earth’s atmosphere blocks most of the radiation from space preventing some electromagnetic spectrum from reaching the Earth because they are absorbed or reflected by the Earth's atmosphere. Visible light and radio waves get through to telescopes on the ground, while X-rays are absorbed by most molecules in the Earth’s atmosphere making it visible only from above the atmosphere.

Some Terms Explained:

Telescope:  is an optical instrument that makes distant objects appear magnified. The purposes of a telescope are to gather light using either a lens or a mirror and resolve detail. There are two basic types of telescopes, refractors and reflectors.

Visible light: covers the range of wavelengths from 400–700 nanometers.

X-rays: range in wavelength from 0.001–10 nanometers. They are shorter in wavelength than Ultraviolet rays and longer than gamma rays. They will pass through most substances, and this makes them useful to see inside things.

Radio waves: the longest waves, longer than 1 meter they have the lowest energy. It is used for long distance communication.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

probably not if net force is zero
